How this service works
UK public data for AI agents, one origin, pay per call: a one-call postcode report, street crime, live flood warnings, property sales and the House Price Index, food hygiene ratings, MP lookup, NHS GPs, pharmacies and dentists, Companies House checks and search, UK working days and bank holidays, and the cheapest card machine provider. Official sources, attribution in every answer, free preview in every 402, failed requests never charged.
Output
A JSON object containing the input start date with its day name and working-day status, the next working day's date and day name, the UK region used, a human-readable summary sentence, and a list of bank holiday names and dates that were skipped to arrive at the next working day.
Example use cases
Payment deadline scheduling
“I need to know the next UK working day after 24 December 2026 in England and Wales so I can schedule a payment that falls due on a business day — and tell me which bank holidays it'll skip over.”
Legal notice deadline calculation
“A legal notice period expires on 27 December — what's the next actual working day after that date in Scotland, skipping any bank holidays?”
Automated invoice due-date check
“My invoice is dated 31 October 2025. What's the next working day after that in Northern Ireland so I know when it officially becomes due?”
Technical details
Endpoint
GEThttps://uk-data.agent-fee-check.workers.dev/working-days/next?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to calculate the next UK working day from a known date with full awareness of regional bank holidays across England & Wales, Scotland, or Northern Ireland. It is preferable over generic date libraries that may not have up-to-date UK bank holiday data, and over manual lookup, especially around variable holidays like Easter. Ideal for scheduling payments, legal deadlines, invoice due dates, or any workflow that must respect UK public holidays by region.
Side effects
- Missing required 'date' query parameter returns an error
- Date not in YYYY-MM-DD format causes a parse error
- Invalid region enum value returns a 400 error
- Dates far in the future may lack bank holiday data and return incomplete results
- Network or worker timeout returns a 5xx error
